What are the types of motors
[2015-03-03]

According to the type of working power supply, it can be divided into DC motors and AC motors
1.1 DC motors can be divided into brushless DC motors and brushed DC motors according to their structure and working principle
1.1.1 Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors
1.1.1.1 Classification of electromagnetic DC motors: series excited DC motors, parallel excited DC motors, separately excited DC motors, and compound excited DC motors
1.1.1.2 Classification of permanent magnet DC motors: rare earth permanent magnet DC motors, ferrite permanent magnet DC motors, and aluminum nickel cobalt permanent magnet DC motors
1.2 AC motors can also be divided into single-phase motors and three-phase motors
According to structure and working principle, it can be divided into DC motor, asynchronous motor, and synchronous motor
2.1 Synchronous motors can be divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors
2.2 Asynchronous motors can be divided into induction motors and AC commutator motors
2.2.1 Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors, and shielded pole asynchronous motors
2.2.2 AC commutator motors can be divided into single-phase series excited motors, AC/DC dual-purpose motors, and repulsion motors
3. Divided by starting and operating modes: capacitor starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting single-phase asynchronous motor, and phase separated single-phase asynchronous motor
4. Divided by purpose: drive motors and control motors
4.1 Division of Drive Motors: Electric motors for power tools (including drilling, polishing, grinding, slotting, cutting, hole enlargement, etc.), household appliances (including washing machines, electric fans, refrigerators, air conditioners, recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.), and other general small mechanical equipment (including various small machine tools, small machinery, medical equipment, electronic instruments, etc.)
4.2 Control motors are further divided into stepper motors and servo motors
5. Divided by rotor structure: cage induction motor (formerly known as squirrel cage asynchronous motor) and wound rotor induction motor (formerly known as wound asynchronous motor)
6. Divided by operating speed: high-speed motor, low-speed motor, constant speed motor, and speed regulating motor
Low speed motors are divided into gear reduction motors, electromagnetic reduction motors, torque motors, and claw pole synchronous motors
Adjustable speed motors can be divided into stepped constant speed motors, continuously variable speed motors, stepped variable speed motors, and continuously variable speed motors. They can also be divided into electromagnetic speed motors, DC speed motors, PWM frequency conversion speed motors, and switched reluctance speed motors
